Information Simple or branched, decorative, densely leafy, shrubby perennial herbs, 0.8–3 m. high; stems subquadrangular, sulcate, thinly pubescent. Leaves subsessile or shortly petiolate, generally discolorous, narrowly oblong, oblong-lanceolate or rarely elliptic, 2–11 cm. long, 0.4–4 cm. broad, margins entire more or less inrolled and scabrid, upper surface glabrescent, lower surface white tomentose, more sparsely so on older leaves so that the glands are visible, cuneate at the base, truncate, rounded emarginate, subacute (rarely acute) and usually apiculate at the apex. Flowers pink, red, purple, or pale mauve with deeper markings. Calyx usually persistent; lobes lanceolate or ovate-lanceolate, 5–10 mm. long, about 2 mm. broad at the base, acute or acuminate at the apex, pubescent. Corolla large, 3.5–7 cm. long, 2–3 cm. in diameter at the throat, thinly to densely pubescent. Filaments arising from a band of hairs near the base of the tube; anthers narrowly oblong, 6 mm. long. Ovary densely white-appressed-pilose, apex emarginate. Capsule subquadrangular, 4-sulcate, 2–2.5 rarely 3 cm. long, 5–6 mm. broad, rather densely pubescent, becoming glabrescent, gradually narrowed into a flattened rather broad beak up to 5 mm. long. Seeds not winged, about 2 mm. long, 1.5 mm. broad, faintly rugose on the sides and faces.

Information Erect annual or perennial herb, simple or branched, 0.8–3 m. high, malodorous. Leaves subsessile or shortly petiolate; lamina cultrate, narrowly oblong, narrowly elliptic or oblanceolate, 2–11 x 0.4–4 cm., margins entire, more or less involute cuneate at the base, truncate, retuse or rarely acute, and usually mucronate at the apex, inferior surface white tomentose. Flowers reddish, pink, or pale mauve with darker markings; calyx lobes narrowly lanceolate or narrowly ovate, 5–10 mm. long, about 2 mm. broad at the base, acute or acuminate at the apex, pubescent; corolla large, 3.5–7 cm. long, 2–3 cm. in diam. at the throat. Capsule narrowly oblong in lateral view, subquadrangular, 4-sulcate, 18–28 x 5–7 mm., rather densely pubescent, gradually narrowed into a flattened rather broad and short beak (TAB. 23 fig. A). Seeds with a double fringe, about 2 x 1.5 mm., faintly rugose on the flanks and faces (TAB. 24 figs. A1, A2).
